Nurse-led patient-centred intervention to increase written advance directives for outpatients in early-stage...

Discussing the evolution of life-threatening diseases and end-of-life issues remains difficult for patients, relatives and professionals. Helping people discuss and formalise their preferences in end-of-life care, as planned in the Go Wish intervention, could reduce health-related anxiety in the advance care planning (ACP) and advance directive (AD) process. The aims of this study are (1) to test the effectiveness of the Go Wish intervention among outpatients in early-stage palliative care and (2) to understand the role of defence mechanisms in end-of-life discussions among nurses, patients and relatives.

A mixed-methods study will be performed. A cluster randomised controlled trials with three parallel arms will be conducted with 45 patients with chronic progressive diseases impacting life expectancy in each group: (1) Group A, Go Wish intervention for patients and their relatives; (2) Group A, Go Wish intervention for patients alone and (3) Group B, for patients (with a waiting list), who will receive the standardised information on ADs (usual care). Randomisation will be at the nurse level as each patient is referred to one of the 20 participating nurses (convenience sample of 20 nurses). A qualitative study will be conducted to understand the cognitive and emotional processes and experiences of nurses, patients and relatives confronted with end-of-life discussions. The outcome measurements include the completion of ADs (yes/no), anxiety, quality of communication about end-of-life care, empowerment, quality of life and attitudes towards ADs.

The study protocol has been approved by the Human Research Ethics Committee of the Canton of Geneva, Switzerland (no. 2019-00922). The findings will be disseminated to practice (nurses, patients and relatives), to national and international scientific conferences, and peer-reviewed journals covering nursing science, psychology and medicine.
